"Lets also say that you may not want people messing with their net_graph while connected to your server. All you'd have to do is enter the command " kac_addcvar net_graph equal kick 0 " and your done."

kac_addcvar <convar> <comparison type> <action> <what the convar should be set to>

So if you use "kac_addcvar net_graph equal kick 0" then KAC will check everyone's net_graph. When KAC receives the convar's status back it will make sure net_graph is set to 0, if not then it will kick them.

I fail to see what your problem is here. You want to prevent people from using net_graph, yes? If so then why are you setting your net_graph to 1?
